RAIL-JOINT.

Specification of Letters Patent.

Patented-A r, it, 1917.

Application filed February 18, 1915. Serial 0. 9,111.

To all whom it may concern:

Be it known that I, MILANBOGDANOVI, a subject of the Emperor of Austria, residing at Cleveland, in the county ofLCLiyahOga and State of Ohio, have invented certain new and useful Improvements in" Rail- Joints, of which the following is a specificazontally, as when in use, the head and foot.

sections of the meeting ends terminate in vertically or transversely disposed abut ments, and the webs have both horizontal or longitudinal and vertical or transverse abutting surfaces.

With this understanding, one object of my invention is to provide the meeting ends of rails with studs and cavities which interlock and hold the abutting surfaces of the two rail sections in close contact. A further object of'the'invention is to provide the meeting ends of rails with interlocking elements which tend to draw and maintain the abutting surfaces of adjacent rail sectlons in close contact. A further object of the invention is to provide for the ready disconnection of rail sections or lengths. A further object of the invention is to provide for avoidance of lodgment of moisture at the junction of rail lengths.

With these and minor objects in view, my invention consists in details of construction and combinations which jwillbe hereinafter described,.and claimed.

In the accompanyingdrawings:

Figure 1 is a view in perspective showing the meeting ends of rail sections or lengths disconnected.

Fig. 2 is a view in elevation looking at the side of the meeting ends of two rails sections connected.

Fig. 8 is a-vertica-l longitudinal section of the rail joint shown in Fig. 2.

In the drawings I have shown the opposite or meeting ends and'B of two sections or lengthsof standard railway rails, each section, of course, having the conventlonal head 1, foot 2, and web 3.

In the practice of my invention, the end A of a rail section or length is shaped by boss lL- and cutting, forging, or otherwise, to form three vertical abutments, 5 and 6, one, ,4, extend-v ing from the .tread tothe web, the second, 5, from the top of the web to the base or foot, and the third, 6, formed by the end of said base'or foot there being two horizontal bearing surfaces or shoulders 7 and 8, one, between the the other, foot 2.

The opposite end B of a rail length is shaped oppositely, having three vertical abutments 9, 10, and 11, to contact with the abutments l, 5 and 6 of the end A of an adjacent rail, and horizontal bearing surfaces 12 and 13 to surfaces or shoulders 7 and 8 of the end A. About midway of the shoulder 7 of the rail end A is an upstandingboss 14 designed to interlock with an elongated cavity 15 in the 7, formed by the top of the web vertical abutments 4: and 5, and 8, formed by the top of the rail under surface of the head of the rail end B,

said rail-end B being provided with a downwardly projecting elongated boss or stud 16 to engage an elongated slot 17 formed in the rail-base or foot 2.

The boss 14 of the'rail-end A is tapered from base to top'a'nd the cavity 15 of the rail-end B is correspondingly tapered, wherebyupon assembling the two rail-ends, the abutting surfaces 4: and 9 of the railheads will be drawn snugly together, and in like manner the stud 16 of the rail-end B and the slot 17 of the rail-end A are ta-.

pered, to the end thatthe several abutting surfaces of the rail-ends will be drawn tightlytogether when they are joined.

-While .the wedging action between the cavity 15 and thestud 16 and slot 17 is relied upon to draw and maintain abutments of the rail-ends in close contact, it will be understood that there will be sufficient clearance between these parts to permit the rail-ends to be easily joined or taken apart, the wedging action being exerted by those surfaces of the parts proximate the adjacent abutments.

The purpose. of providing a slot 17 instead of a mortiseior recess in the rail-foot to receive the stud 16, is to admit of drainage for any moisture. that may enter the joint between rail-ends, and'from the construction shown it will be noted that to disconnect this lock-joint it is only necessary to raise the end B sufficiently for the stud 16 of the rail-end B to clear the slot 17 of rest upon the corresponding the rail-end A, the Wedging boss 14 being of less height than the stud 16 Will clear itself from the recess 15 before the lower end of said stud 16 has risen free from the drain ing slot 17.

I claim: 7 I

A locking joint for the meeting ends of railway rails comprising three unbroken transverse abutments terminating the head, foot and Webs of the rails; longitudinal ,bearing surfaces extending between said abutments; a longitudinally tapered drainage slot in the foot and a tapered Wedging five cents each, by Washington, D. 0.

boss upstanding from the Web of one rail and a longitudlnal taslot in the rail-foot.
